MACHINE FOR MAKING MOPS.

Patented June 23, 1908.

Serial No. 415,246.

To all whom it may concern:

Be it known that I, LoUIs STooKER, citizen of the United States, residing at Louisville, county of Jefierson, and State of Kentucky, have invented certain new and useful Improvements in Machines for Making Mops, of which the following is a specification, reference being had therein to the accompanying drawing. I I

This invention relates to a mop making machine, and particularly to a structure wherein the flexible absorbent fibers are connected together by a strip sewed thereto.

The invention has for an object to provide a construction of cord or yarn supporting means by which the yarn may be held under tension and while in this condition moved relatively to a sewing mechanism for the purpose of connecting the cords by a strip sewed transversely thereon intermediate of their opposite ends.

A further object of the invention is to provide means for automatically placing the tension upon the cords while one end thereof is held by a supporting mechanism so that in the movement of this mechanism in engagement with the cords they are drawn from the supply under tension.

Another object of the invention is to pro vide a novel and improved construction of gripper carried by the supporting mechanism by which the cords or yarn may be held firmly under tension before and While being connected by the strip attached thereto.

Other and further objects and advantages of the invention will be hereinafter fully set forth and the novel features thereof defined by the appended claims.

In the drawing :Figure 1 is a perspective view of the invention; Fig. 2 is a similar-view of the gripper carried by the support; Fig. 3 is a perspective view of the gripper in closed position; Fig. 4 is an end elevation of this gripper; Fig. 5 is a central vertical section through the tension device; Fig. 6 is a section on the line 6-6, Fig. 5; Fig. 7 is a vertical sectionv on the line 7 -7 Fig. 1.

Like numerals refer to like parts in the several views of the drawings.

The numeral 10 designates the frame of the machine which may be of any desired construction or configuration and is provided with forwardly extending arms 11 and 12. The frame is provided with bearings 13 in which the shaft 14 is mounted for both reciprocation and rotation, said shaft having secured to its outer end a transversely extending bar 19 disposed at substantially a right angle to the shaft and comprising carrying means for the cord or yarn grippers 15. This bar'is provided at op osite ends with spring pressed bolts 16 suitab ymounted to extend beyond the ends thereof and to rest in contact with the guide plates 17 on the arms 11 and 12 when the bar 19 is in horizontal position, as shown in Fig. 1. Each of these bolts is provided with an operating handle 18 by which they maybe readily shifted for the purpose of rotating the bar with its grippin devices.

Any desired orm of grip ing device for holding the cords may be emp oyed, but a desirable construction thereof is shown in Figs. 2, 3 and 4, and comprises the frame 20 secured to the bar 19 in any desired manner, and having a laterally extending arm 21 upon which a series of fixed open jaws 22 are secured between which the strands of cord or yarn are passed, While at the opposite ends of these jaws guide arms 23 are provided. At the base of each of the fixed aws 22 a movable jaw 24 is mounted by means of the pivot 25 and thus adapted to swing toward the base of the gripper and toward the adjacent jaw. The lower ends 26 of the movable jaws 24 are connected by the bar 27 for simultaneous operation, and this bar is pivoted to a link 28 which at its opposite end is pivoted at 29 to the o erating lever 30, the inner end 31 of this ever being pivotally mounted upon the lug 32 of the gripperframe. From the bar connecting the movable jaws an extension 33 is provided, and a tension spring 34 extends therefrom and is fixed at 35 to the guide frame 36 which is disposed at the opposite side of the gripper from the jaws and over which the yarn passes in the operation of the machine. with a stop or lug 37 to limit the lateral movement of the yarn thereon when the gripper is moved toward the sewing mechanism. This spring normally retains the jaws in gripping position, as shown in Fig. 3 with the operating lever lowered. When it is desired to open the jaws and to release the yarn, this lever is raised into the position shown in Fig. 2 and the spring placed under tension. For the purpose of separating a-completed mop This frameis provided fabric. from the remainder of the strands from which it is made a cutter guide 38 is mounted at the side of the gripper next the rotatable shaft by which it is carried. This frame comprises bifurcated members 39 at its opposite ends between which a saw 40 or other cutting device may be inserted, as indicated by dotted lines in Fig. 3.

For the purpose of connecting the strands forming the mop fabric a strip is extended transversely of the length thereof and sewed thereon. This sewing may be effected by the relative movement of the sewing mechanism and the supporting mechanism so that one thereof is brought into the field of action of the other. In the present instance the supporting mechanism is provided with means for imparting thereto a movement laterally of the strands carried thereby and this may be effected by any desired means, for instance, a feed nut 41 carried by a sleeve 42 which is loosely mounted upon the shaft 14 and held against lateral displacement by means of set collars 43 at its opposite ends. This nut engages a screw or worm shaft 44 mounted in bearings 45 upon the frame 10. Upon this frame a sewing mechanism 46 of any desired character may be rigidly secured in a position substantially midway between the opposite gripping devices upon the rotatable bar 19. The tape or strip 47 to be applied to the cords may be carried by a spool 48 mounted upon the frame and suitable guides 49 carried, to the point of a plication where it is passed by hand entire y around the cords before the stitching action. For

the purpose of driving these several parts a.

main driving shaft 50 is mounted upon the frame and provided with a, fast pulley 51 and, a loose pu ey 52 at one end of the frame. This shaft is also provided with a driving pulley 53 from which belt 54 extends to the pulley 55 upon the shaft of the screw 44.

For the purpose of driving the sewingmechanism simultaneously with the feedingaction a pulley 56 is provided on the shaft 50 and the belt 57 extends therefrom to the dri ving wheel 58 upon the sewing mechanism. The feed nut 41 is raised into operative engagement with the screw 44 by means of the treadle 59 and a rod 60 extending therefrom to adepending lug 61 from the nut- This rod may be provided with a spring connection 62 by which a yielding contact between the nut and screw is secured. The treadle 59 is also connected with the belt shifter 63 through which the driving belt 64 for the pulleys 51 and 52 passes. This shifter is carried by the depending arm 65extending downward from the pivotal bearing 66 upon the frame and connected to the lever 67 which lever at its opposite end is connectedwith the rod 68 extending to the inner end of the treadle 59. This rod is provided with a suitable weight 69 for restoring the belt to the loose pulley nut thus throwing the same out of engage-' ment with the screw which is permitted. by the spring connection 62 with the treadle.

A preferred form of the automatically operated tension mechanism is illustrated in detail in Figs. 5 and 6 and comprises a frame 72 supported 'at one end of the machine in alinement with the grippers. This tension device may be mounted upon the end bar 12 by means of the bracket 73 and is provided with a guide 74 through which the strands of cord or yarn pass on their way to the grippers. provided over which these strands pass. The guide is also formed with a vertically disposed track or way 76 in which a tension carriage 77 is slidingly mounted, the weight thereof being counterbalanced to any desired extent by means of the weights 78 connected tothe carriage by a cordv or cable 79 which passes over suitable pulleys 80 and 81 mounted upon the frame. The carriage is provided. with a roller 82 under which the cord passes, and the carriage is adapted to be moved downwardly to draw a supply of cord by the cable connection 83- passing over the guide pulley 84 and wound upon a drum 85 on the shaft 86 mounted at the base of the machine. This shaft is provided with a fast pulley 87 and, a loose pulley 88 suitably mounted thereon; and driven from the belt connection 89 which is independent of the driving mechanism for the feed and sewingparts. The belt 89 is adapted to be shifted y an angle lever 90 pivotally mounted at 91 in the bracket 92 and connected by the link 93 with the crank arm 94 from the rock shaft 95 mounted upon the machine frame, as shown in Fig. 1. This shifting lever is automatically moved to place the belt in driving position, asshown in Fig. 5', in the swinging or rotary movement of the grippers, as the bar 19 thereof is provided with inwardly projecting pins 96 at opposite ends which their travel contact with thepivoted lever 97 and shift the rock shaft 95. This lever is pivotally mounted upon. a fixed part at its lower end 98 and connected by the link 99 with the crank arm 100'carriedv by the shaft 95. When the parts are in the position shown inFig. 5, the; cable 83 iswound upon the drum on. theshaft 86 until the carriage reaches the lower part. of the tension frame when the belt is shifted to the loose-pulley by means of the stop 101 mounted upon this At the base of this guide a roller is shown in Fig. 5.

carriage and adapted to engage the trip arm 102 secured to the rock shaft'95, as clearly The cord strands pass under the roller 82 of the carriage and thence over the roller 103 carried by the bracket 7 3 and under the roller 104 mounted upon the frame from whence they pass to the gripping devices before described.

From the foregoing description the operation of the machine will be apparent, and with the parts in the position shown in Fig. 1 with the cord strands held under tension by the grippers the tape is carried around these strands by hand and the treadle then depressed to apply power to the main driving shaft which actuates the sewing mechanism and simultaneously the feed of the grippers carrying the cords to the sewing mechanism. This feed continues until automatically re leased by the striker removing the traveling nut from its screw when pressure uponthe treadle is released stopping the sewing and feed mechanisms and permitting the bar carrying the grippers to be drawn in sliding contact outward to the front of the machine by hand where the cords at the underside of the uppermost gripper are cut or severed by any suitable tool. The opposite end of the completed mop is removed from the under gripper by opening the same, while the ends of the strands are retained by the upper gripper, and the bar carrying these grippers reversed in position by withdrawing the slide bolt at the right and carrying the bar for a half revolution and reversing the position of the grippers, and during this movement the actuating lever of the grippers engages the bar 105 atthe front of the machine and'is thrown downward into locked position, while the bolt rests upon the guide plate at the left end ofthe machine. travel the actuating lever of the tension mechanism has been shifted and the carriage thereof drawn downward placing the strands in the grippers under tension and also draw ing a fresh length from the supply so that in the subsequent rotation of the grippers the carriage is raised by the draft upon the strands and a proper tension maintained thereon at all times. The downward movement of the tension carriage shifts the driving belt for the shaft thereof to the loose pulley thus stopping the travel of the carriage.

It will be seen that the invention presents a machine adapted for the manufacture of mops, brushes and similar articles in which a series of flexible absorbent strands are connected together by an encircling band which is sewed thereto. Such mops are used in connection with handles or clamping devices to which they may be attached.
